Feature
I. Multi-Dimensional Contaminant Simulation System
The chamber employs triaxial particulate injection technology that transcends basic dust exposure:
• Variable Profile Dispersion: 8 programmable particle distribution modes (laminar flow, turbulent vortex, gravitational settlement)
• Intelligent Particle Sizing: Real-time laser diffraction monitoring (0.1–200µm range) with dynamic density compensation
• Electrostatic Charge Control: ±15kV adjustable tribocharging to simulate real-world particulate adhesion
• Thermal Cycling Integration: -70°C to +180°C conditioning during dust exposure
